According to Watkins, this is probably from PIE *sai-tlo-, with instrumental element *-tlo- + *sai- "to bind, tie" (see sinew), extended metaphorically to successive human generations as links in the chain of life. Another theory connects it with words for "seed," from PIE root *se- "to sow" (see sow (v.), and compare Gothic mana-seþs "mankind, world," literally "seed of men").

Used in ecclesiastical writing like Greek aion "of this world" (see cosmos). It is source of French siècle.
